  • Publication number: 20090072644
    Abstract: A thrust magnetic bearing system separates magnetic circuits of electromagnets from those of permanent magnets so that each permanent magnet produces a bias magnetic field while each electromagnet functions only to control the position of a rotating body, thereby achieving desired displacement and current stiffness without flowing a bias current through the electromagnet. The magnetic bearing system includes a thrust displacement sensor and a thrust magnetic bearing to float a disk floating body based on displacement information detected through the displacement sensor. The magnetic bearing includes a donut permanent magnet, a pair of electromagnets connected in series to form an inductor at both sides of the donut permanent magnet, and a pair of magnetic poles provided opposite each other outside the pair of electromagnets. The magnetic bearing floats the floating body through a bias magnetic flux generated by the permanent magnet and a control magnetic flux generated by the electromagnets.

  • Publication number: 20080161169
    Abstract: A computer-controlled training apparatus for spine-stabilizing musculature is designed to tilt an upstanding user by a predetermined angle in accordance with a training program recorded in a computer so as to cause a reflexive movement for the user based on the human body's sense of balance for maintaining posture. The training device for spine-stabilizing musculature includes a base stand, a pitching unit having a pitching plate installed above the base stand in a vertically pivotally rotatable manner, a rolling unit having a rolling plate rotatably coupled to the pitching unit, a securing unit mounted to the rolling unit for securing the user's body at a fixed position, and a cover for preventing the pitching unit and a part of the rolling unit below the rolling plate from being exposed to the outside.

  • Publication number: 20070277128
    Abstract: In one embodiment of a system for sensing the shape of a chip, a support plate is provided that preferably includes at least one chip mounted thereon. A lower lighting unit is preferably disposed below the support plate to emit light through the support plate and around or between the chip(s) toward an optical sensing unit, with a portion of the light emitted being blocked by the opaque chip(s). The optical sensing unit preferably senses the light that passes through the support plate and around or between the chip(s), but not the light that is blocked by the chip(s). In this manner, the shape of the chip can be more accurately determined, even when it is deformed within an acceptable range. A method for using a system constructed according to the principles of the present invention is also provided.

  • Patent number: 7255074
    Abstract: A linear EMV actuator uses a permanent magnet and an electromagnet in which EMV operation for opening/closing an exhaust valve and an intake valve makes valve operations linear. As a result, the valve undergoes a soft landing and active control of an amount of opening of the valve. The linear EMV actuator includes an upper core and a lower core, an armature, an actuator spring and a valve spring. Also included are a permanent magnet, an upper coil and a lower coil connected to each other in series thereby forming one electromagnet, a displacement sensor, and a position controller.
